Hydraulic vertical hinge shaft dismantling device

Abstract

A hydraulic vertical hinge shaft dismantling device comprises a coupling block, a serial connection block, adjustable jacking lead screws, hexagon nuts, an upper platform, a lower platform, a lug seat, a sliding connection device, a push-pull jack, a telescopic jack, an operating valve set and a bidirectional lock. The upper platform and the lower platform are connected through the sliding connection device, and the upper platform can move up and down relative to the lower platform. The push-pull jack is horizontally fixed on the upper surface of the upper platform, the serial connection block is fixed at the front end of the push-pull jack, the coupling block is connected to the serial connection block, the adjustable jacking lead screws are installed on the two sides of the push-pull jack through the hexagon rectangular nuts, and the telescopic jack is arranged between the upper platform and the lower platform. The height of the device can be adjusted, and dismantling and pulling of hinge shafts at multiple positions can be achieved; long-time high-intensity operation of operators is avoided, and irreversible consequences caused by using a destructive mode are avoided; and not only can the labor production efficiency be improved, but also the labor intensity of workers can be greatly reduced, the cost investment of new parts and the like is reduced, and the purposes of improving the quality and improving the efficiency are achieved.

Description

technical field

[0001] The invention relates to an auxiliary machine, in particular to a hydraulic vertical hinged shaft removal device used for dismantling the hinged shaft during the inspection and maintenance of coal mine fully mechanized mining equipment such as hydraulic supports. Background technique

[0002] The hydraulic support of coal mine fully mechanized mining equipment has become one of the main equipment of coal mine mechanized fully mechanized mining. With the increase of service life and the continuous increase of production tasks, the service period of batch supports is continuously extended. For example, the parts connected by hinge shafts, such as the cover beam and the top beam, and the cover beam and the base, all have different degrees of deformation. In addition, the underground operation environment is complex, and the joint shaft and the joint hole are under the influence of coal slime and humid environment, causing problems such as corrosion and ga...
